Title: Preparation of phenol from benzoic acid
IPC: C07C37/56
Filed: 1963-01-22
Abstract: The invention relates to a process in which phenol is prepared by reacting benzoic acid vapour with molecular oxygen, in contact with metallic copper and in the presence of water vapour. Preferably the copper is applied to a carrier e.g. such as the oxides of zinc, calcium, aluminium, titanium, cadmium, magnesium, barium, cerium, or silicon.  In an example benzoic-acid vapour, obtained by passing nitrogen through molten benzoic acid, water vapour and air are passed through a tubular reactor containing a catalyst consisting of copper on magnesium oxide (50% by weight of copper) at a temperature of 250 DEG C., to produce phenol.

Title: Antenna system for modulated-carrier signal receivers
IPC: H03H2/00
Filed: 1941-03-04
Abstract: 547,677. Wireless receiving circuits. HAZELTINE CORPORATION. March 4, 1941, No. 2933. Convention date, March 23, 1940. [Classes 40 (iii) and 40 (v)] Relates to receivers which can be used at will either with a loop antenna or with an antennaground system and in which the antenna-ground system 17, 18 is coupled by switch 19, 20 to the receiver 13 through the loop aerial 22 by means of an impedance 21. According to the invention this impedance tunes the antenna system 17, 18 at a frequency near the lower end of the band covered by the loop aerial. When the antenna 17, 18 is not in use, a condenser 23 tunes the impedance 21 to the intermediate frequency of the receiver 13, thus forming a trap circuit to prevent interference at this frequency. In the modified circuit shown in Fig. 6, the inductance 21 is replaced by a small inductance 30 coupled to the loop antenna and a larger inductance 29 having distributed capacity C 29 which makes the coil 29 resonant at a frequency above the tuning band. A resistance 31 damps the primary circuit whether the switch 19 is open or closed, thereby improving the uniformity of response of the antenna system and reducing the effects on the alignment of the tuned circuits of the receiver due to connecting in the antenna 17. In the circuit shown in Fig. 4, the antenna 17 can be connected to the loop aerial by a band rejector filter having two series inductance arms 24, 25 and a series-tuned shunt arm 26, 27, the circuit 24, 26, 27 including part of the loop being sharply tuned to the intermediate frequency to reduce interference, and the circuit 25, 26, 27 including the capacity of the antenna 17 being broadly tuned to a frequency at the lower end of the frequency band. A series resistance 28 has a similar function to the resistance 31 in Fig. 6. The inductance 21, Figs. 1 or 30, Fig. 6, may be a coil of cross-sectional area small in comparison with that of the loop aerial and arranged near one end or comer of the loop, Figs. 2a, 2b (not shown).

A welt indenting machine has a frusto-conical toothed indenting wheel 10 supported, in a freely rotatable manner, on a pin 26 in the lower end of a connecting rod 32 which is pivoted at 62 to the forward end of a guide link 64, the opposite end of which is pivoted to swing about a fixed pivot 66 (not shown) on the machine frame. The connecting rod 32 is driven by a crank comprising a crank pin 36 supported in an eccentric bore in a sleeve 38 which is supported in an eccentric bore in a shaft 40 driven from a motor 60. To permit the amplitude of impulses given to the wheel 10 by the crank pin to be varied, the sleeve 38 and crank pin 36 are adjustably 'held in position by set screws 42, 44. The fulcrum 62 is also adjustable in an arcuate slot in the link 64 to vary the diameter of the orbital path of the wheel 10. A guard 12 protects the upper and serves as a guide therefor. The wheel 10 may be heated by a jet from a gas pipe 68. The work table 14 is carried by a pair of parallel arms 70, to a cross bar 72 connecting the forward ends of which is attached a rod 94, on a collar 110 and spring 112 on a rod 106 connected to which is supported a heavy inertia block 104. A treadle lever 120 may be operated to make and break a toggle 106, 116 with the aid of a spring 122 to raise and lower the table 14 to permit the work to be inserted and removed. On release of the treadle the toggle straightens and the work table, except for spring 112, is rigidly supported. The table 14 is adjustably supported on an arcuate slide 132 the axis of curvature of which is on a line tangential to the periphery of the upper surface of the table and perpendicular to the axis of the wheel 10. A block 140 which supports the slide 132 is adjustable in position in the direction of work feed to fix the axis of the table 14 in relation to the centre of the guard 12 to give a component of cross feed to hold the upper against the guard if desired. Orbital movements of small amplitude are given to the indenting wheel 10 through a universally jointed shaft 158 driven from the motor 60 through reduction gearing. These are too rapid to affect the inertia block 104. Specification 580,777 is referred to.

Class 142(2) In a positive let-off motion in which rotation of the beam is controlled by the tension of the warp acting on a movable tensioning roller, a feeler adjusts the leverage of a balance weight for the tensioning roller in accordance with the amount of yarn on the beam. The tensioning roller is locked in position during shedding. The warp passes round a back rest constituted by a roller whose bearings can be clamped to produce a braking effect. Controlling let-off. The warp beam 1 is rotated by a ratchet-operated worm drive (not shown), the pawl being actuated by a rod 16 from a slide 18 oscillated by the slay 29 through a link 26. The slider is slotted to embrace a fixed pivot pin 19 upon which it is vertically movable to alter the ratio of its two arms, and hence alter the stroke of the pawl The slider is supported by a roller 22 running in an arcuate slot 23 in a lever 24 which is coupled by links 33, 38 to a shaft 43 carrying a tension roller 46, whereby an increase in the tension of the warp depresses the lever 24 to increase the stroke of the pawl. The tension roller is loaded by a weight 61 on a lever 36 pivoted at 37. To compensate for the changing line of action of the warp on the tension roller as weaving proceeds, a feeler 77 resting against the yarn on the beam is coupled to the weight by links 72, 62 to move the weight further away from the pivot 37 as the beam empties. To prevent excessive oscillation of the shaft 43 during the loom cycle, a brake shoe (not shown) is pressed against a sector 42 by a cam when the slay is at the rear part of its stroke.
